Please Help - Find the equation of the line tangent to the curve 2(x2+y2)2=25(x2−y2)
at the point (−3,−1).

When the equation of this tangent line is written in the form y=mx+b,

40 minutes

step-by-step explanation:

add the time and multiply by 2

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

the answer is b

combine all like terms then its just a 2 step equation
